FAN ATTACHMENT FOR ROCKING-CHAIRS.

SPECIFICATION forming part of Letters Patent No. 666,310, dated January 22, 1901.

Application filed May 1, 1900. Serial No. 15,051. (No model.

To (tZZ whom it may concern:

Be it known that I, OSCAR HERRMANN, a citizen of the United States,residing in New York, borough of Manhattan, State of New York, have invented certain new and useful Improvements in Fan Attachments forRocking- Chairs, of which the following is a specification.

This invention relates to an improved fan attachment for rocking-chairs; and the object of the invention is to provide a powerful and at the same time comparatively simple fan attachment which may be applied readily to any rocking-chair of the ordinary construction; and the invention consists in the combination, with a rockingchair, of a pivoted toothed segment, a pusher-rod attached to said segment, a shaft supported in suitable bearings adjustable upon the rocking-chair, a pinion keyed to said shaft and adapted to mesh with the toothed segment, a fan supported upon the rocking-chair on a suitable shaft, and motion-transmitting mechanism between the pinion-shaft and fanshaft, substantially as hereinafter described; and the invention consists, further, in certain details of con struction and com bi nations of parts,also described and claimed hereinafter.

In the accompanying drawings, Figure 1 represents a side elevation of a rocking-chair wit-h my improved fan attachment applied thereto, parts being shown in section; and Fig. 2 is a vertical section on line 2 2, Fig. 1, showing the fan attachment as viewed in the direction of the arrow in Fig. 1.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A represents a rocking-chair of the usual construction, and B one of the rockers of the same. To the inside of the rocker B are attached, by suitable fastening-screws, three slotted upright standards Z) 1) 5 of which the two b I) serve for supporting the bearings b for a horizontal shaft 0, while the longer intermediate standard serves for supporting the shaft of an oscillating toothed segment D. The journal-bearings for the shaft 0 are secured to the standards in any suitable manner, and the shaft of the segment is preferably supported upon the standard I) by a washer and clamping-nut, as shown in Fig. 2, so as to be held in position thereon in such manner that it can oscillate freely on said shaft. The toothed portion (1 of the segment is pivoted at its upper end to the upper arm of the segment and provided at its lower end with a socket c, in which the pin-shaped end (1 of the lower arm is guided, a helical cushioning-spring e being interposed between the socket e and a collar 6 of the lower arm, as shown in Fig. 1. The teeth of the bar d may be made of arched shape and mesh with the teeth of a crown-pinion f, which is secured by a set-screw to the horizontal shaft 0, when the segment is moved in upward direction. When the segment is moved in downward direction, the teeth of the crown-pinion are not engaged by the segment. To the upper arm of the segment D is applied, by a suitable clamping-screw, a slotted pusher-arm E, which is arranged, preferably, at right angles to the arm of the segment and at such a height as to contact with the floor at each backward motion of the rocking-chair, so

as to lift the segment D and produce by the meshing of its teeth with the crown-pinion the quick rotation of the horizontal shaft 0. When the rocking-chair is moved in forward direction, the segment, by gravity, returns in downward direction relatively to the pinion, its teeth passing over the pinion-teeth without meshing in the same. On the downward movement the spring 6 yields and permits the inward swinging of the toothed bar (I of the segment sufficiently to enable it to move easily upon the pinion-teeth. The rotary motion imparted to the shaft 0 is transmitted by a pulley g, keyed to the same, and an endless cord g to a pulley g on the shaft 9 of the rotary fan G, which is supported on an upright arm or standard G, that is attached to one of the arms H of the chair, as shown in Fig. l. A guard G for the fan is supported on the arm G. The transmittingcord g is guided on suitable rollers 9 which act also as tension-pulleys and which are attached to the seat H and arm H of the chair. The lower pulley g is made in the nature of a fly-wheel and serves thereby to keep the fan in motion during the forward oscillation of the rocking-chair during the time when the segment and pusher-rod are returning into lowered position. By the intermittent meshing of the toothed segment with the pinion intermittent rotary motion in one direction is imparted to the shaft C and by the transmitting cord and pulleys to the fan. After the chair has been rocked back and forth several times the motion becomes continuous by means of the fly-wheel pulley 9, so that a continuous draft of air is produced by the fan.

The slots in the straps and in the pusherrod permit perfect adjustment of the parts, so that the attachment can be applied to rockers of varying sizes. By adjustment of the pusher-rod the amount of impulse to be given to the pusher-rod can be regulated, and thereby the strength of the draft controlled.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a rocking-chair, of a pivoted toothed segment, a pusher-rod attached to said segment, a shaft supported in suitable bearings adjustable upon the rockingchair, a pinion keyed to said shaft and adapted to mesh with the toothed segment, a fan supported upon the chair on a suitable shaft, and motion-transmitting mechanism between the pinion-shaft and fan-shaft, substantially as set forth. 6

2. The combination, with a rocking-chair, of a segmentpivotally supported on the frame of the same, said segment being composed of upper and lower arms and a toothed portion pivoted to one of said arms and spring-cushioned and guided on the other arm, a shaft supported in suitable bearings upon the rocking-chair, a pusher-rod attached to one arm of the segment and extending below the rockers of the chair, a pinion keyed to the shaft and adapted to mesh with the toothed portion of the segment, a fan suitably supported upon the chair, and motion-transmitting mechan ism between the pinion-shaft and the fanshaft, substantially as set forth.

3. The combination, with a rocking-chair, of slotted standards attached to the same, a toothed segment pivoted to one of said standards, an adjustable pusher-arm attached to said segment and extending below the same and below the rockers of the chair, bearings adjustably supported on said standards, a shaft supported in said bearings, a crownpinion keyed to said shaft and adapted to mesh with the teeth of the segment, a fan and fan-shaft supported in suitable bearings upon the chair, and motion-transmitting mechanism between the pinion-shaft and fan-shaft, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
